Unicat?

I just finished building a Unicat 2.4 and am quite pleased how it turned out...though Ive yet to float test it.

Any other Unicat owners here?

Re: Unicat?

Nice work! Would be curious how she rows.

Do you plan for an outboard?

Thanks!

Yes, a smallish OB, just depends on what is availble when I finally get her over to Bocas del Toro (where my cat is stowed).

The hull shape should track quite well for rowing. It is in inverted "V" and has keel strakes. You can see both the keel strakes and hull shape in foto below.

Re: Unicat?

And where’s where’s the waterline? Is the bow usually up and out of the water?

It’s an interesting boat. Kind of like a pram/cat hybrid.

Definitely looks like she’ll slip through the water with ease for rowing.

Curious to her how she works out with the cat as a tender

Based on the designer's web site videos the hollow formed under the bow by the inverted "V" hull shape is usually out of the water.

I think of "unicat" as being sort of like "unibrow"...two hull shapes joined by the inverted "V". Yes, very much like a pram/cat hybrid. The inverted "V" makes the build a little more complex, but that combined with the longitudinal and transverse bulkheads make a very stiff structure.

Its stitch and glue constructruction with fiberglass over plywood. I built mine of 5mm plywood, 400gsm glass, and epoxy. The spec weight is 35kg. Ive not weighed mine, but I expect Im within a few kg of that. I added a little more glass in critical areas. Two people can easily lift it.

Designer's site has video of it underway:

Re: Unicat?

De nada.

Another cool bit of this project is that I first built a Maslow CNC machine and used it to cut all the panels. This made the cuts more accurate and avoided the usual hand build method of cutting outside the plan lines and then fairing down to the line. Link to Maslow CNC:

Build pics at the link below. Includes a video of the Maslow cutting the panels.
